Henan Huanyu Power Source is capable to design and produce over 100 types and models of nickel-based batteries, with sintering technology and foam and edge-welding technology, and foam and tab technology respectively. Of the three types of batteries, sintered nickel-cadmium battery (Ni-Cd) is regarded as the most reliable portable power source available now in the world.
Huanyu nickel based batteries have the following advantages:
Ø Excellent performance-price ratio
Ø Reliable safety
Ø Long cycle life
Ø Fast charging ability and superior high-rate discharge
Foamed Ni-Cd batteries:
Foamed Ni-Cd batteries not only have the excellent performance of Ni-Cd battery, such as superior high-rate discharge, longer cycle life, fine high and low temperature performance, and reliable safety, but also possess high capacity density and good cost advantage, which makes it another milestone in the development of Ni-Cd battery.
Sintered NIi-Cd batteries:
Sintered Ni-Cd batteries have the following unmatched performance characteristics: superior high-rate discharge, longer cycle life, wider range of operation temperature, lower self-discharge rate, ability to prevent mechanical and electric power abuse, lower internal resistance, and reliable safety. They are the most preferred power for different kinds of power tools.
